FASTENING DEVICE FOR LEGGINGS.

in the art to which it pertains to make and use the same, reference being had to the accompanying drawing, which forms a part of thisspecifioation.

y invention relates to devices for firmly fastening or looking together the lower edges of the two overlapping flaps of leggings and the like and has for its object to provide an improved device of this character simple in construction, cheap and easy to manufacture, readily applicable to the great durability and efficiency in use and renderingit possible to readily engage and disengage the said twoflaps by hand whilst absolutely preventing them from disengaging themselves accidentally.

Hitherto, the two overlapping flaps of leggings have been fastened together by different devices such, for instance, as straps attached to buckles ior loops, laces passed through a series of eyeleted holes, or else staples, clips, tongues or the like fixedly secured to one flap and engaging similar members on the vices. However the fastening device most commonly used in th'erpast consists of an upper strap attached to buckles on both flaps of the legging and asteel plate spring retained adjacent the longitudinal edge of the outer flap and engaging-a metal socket or similar means secured adjacent the lower end of the inner flap. This fastening device as well as the other ones above referred to has a serious drawback in that it does not provide a rigid locking means for the two overlapping flaps of the legging which can thus disengage themselves duringuse. One feature of the present mvention consists in providingthe inner face of the outer" flap of the legging with the overlapping usual fixed steel plate spring which extends adjacent the over the greater part of the length thereof but terminates at asho-rt distanceyfrom the lower edge of the legging, and in so constructing the said spring that its lower free extremity is reduced in width and tongueshaped for engagement with a suitably other flap, or similar dc longitudinal edge of saidflap 'gitudinal view of the inner flap and having a novel construction as Wlll appear hereinafter. The tongue-shaped extremity of the plate spring is bentlengthwise outwardly, i. e., towards the-opposite flap, and is formed centrally at a suitable position intermediate its ends with a hole, preferably circular in shape.

A further feature of the present invention consists in'providing the outer face of the lnner or underlying flap of the legging with PATENT OFFICE.

The flat intermediate portion or platfgrni of the bridge-shaped socket is formed centrally with an inwardly projectingboss, preferably circular in shape to match with the hole i formed in the extremhaving a diameter slightly smaller than that of the said hole.

The operation of this device ily understood from the foregoing description with reference to the figures of the;

drawing; ll'o fasten or-lock together the two overlapping flaps of th legging,-- all that is necessary is to engasethe'rounded tip k -of'thetongue-shapedextremity ef the plate spring.

and eansing it to slide lightly thereupon. Owing-to the resiliency of-the spring. B; when once the boss (lwhas entered the hole 6 it can 'notwlisengage itselflso that thetwo flaps are firmly locked together. If now. it-

is desired to tin-fasten the-said two: flaps, this can. be; performed very :easily by the wearerhimself; All that is necessary for him is then to press down (by-hand) the reg-ionvof the outer fiap' adjacent the locking devicc somewhat to the rear of sam Whilst simultaneously pulling-upward the saidlouter to the resiliency-of the spring and the peculiar-form: of the hole vI formed" flap; Owing in" the tongue-shaped" extremity of said spring, this combined pressure and tractionforces'the boss formedin th socket'out'of the hole formedinl' the said? tongue-shaped extremity; whereby the latter may readily he-disengiagedfrom the said socket; thus un fastening the two' flaps.

- While I :have 'describedthe"preferred con struction. of fastening devioe embodying-my:

invention and the operation thereof, I am aware that certain slight changes of construction or certain omissions of parts may be made without departing from the spirit of the invention as hereinafter claimed.

I claim l. A fastener for connecting overlapping pieces of fabric comprising a member adapt-- ed to be secured to one piece of fabric and provided at one end with an outwardly-hr clined spring tongue in which an opening is formed: and a companion member adapted to be secured to the other piece offabric and consisting of a bridge-piece embodying a If; flat central platform formed with a boss which PIOJGCtS inward from its inner face, and T-shaped ends, a securing plate adapted to be positioned against the inner face of the second-named piece offabric, and a counterplate adapted to be inserted between said platform and the outer face of said second-named piece of fabric and having slots to enable the stem portions of the ends of the platform to be passed therethrough and through the fabric and bent inward against the face of the counterplate; said tongue adapted to be inserted between the platform of the bridge piece and the counterplate to enable the boss on said platform to snap into engagement in the opening in said tongue.

comprising a said bridge-piece having a central bosswhich projects inwardly from its under face toward said plate; said tongu adapted to be inserted between the central portion of the bridge-piece and said. plate to enable said boss to snap openin in said tongue.

3. A fastener for claim 2, in which the plate projects up wardly beyond the bridge-piece and is provided with a depressed upper edge to guide the tongue toward the bridge-piece during its insertion beneath the same and to prevent said tongue from catching behind said plate.

4. A fastener for leggings, according to claim 2, in which the plate projects upwardly beyond the bridge-piece and is provided with a bent, arcuate upper edge to guide the tongue toward the bridge-piece during its insertion beneath the same and to prevent said tongue from In testimony whereof I edit: my signature.
